to be honest, my encounter with the Umobile reps have been good so far. I MNP-ed my number from UOX to Umobile prepaid two years ago at their service centre in Jusco AU2, everything was done smoothly, the rep was efficient and everything was done within 15 minutes. my number was successfully ported after a few hours, not too shabby.
Called their careline last year over a problem that my friend had with no connectivity (postpaid+S2) and they resolved it within that call itself.
Bought a special FB deal that Umobile had for postpaid in January early this year, (around 260 for 6 months of 5gb broadband data + free usb modem) at their service centre in Times Square and they know about the deal and everything was done within a few minutes.
Called them again a few weeks ago at 3am

to clarify about the account status for my friend (He is studying overseas and his account was going to expire before he came back) and the rep handled it nicely, even at 3am
so yeah, my experience with their customer service has been good so far.
Just prepare all the necessary information before contacting them, and speak nicely to them, and hopefully everything would be smoothly resolved.

better check with their customer careline, my previous experience with Maxis was they will still honour the pricing of the original plan, nothing is changed. Not sure about Umobile though
